"To all whom it may 00mm..-

' dent of Montclair, in'the county of Essex and State -of New Jersey, have inventedcer- 'ta'in new and useful Improvements in a Hoistingand Conveying Device, of which the "following is a specification.

My invention relates to new and useful improvements in hoisting and conveying 'de-' woes of the cableway type, and is more particularly designed for use in logging operaments to be fully described hereinafter, and the novelty of which will be particularly 'tions, although it is capable of many other uses without in any way departing from the spirit and scope of my invention.

The invention consists in the 1l11p1'OV8- pointed out and distinctly claimed.

I'have fully and clearly illustrated a 'pre-;

ferred embodiment of my invention in the accompanying drawings to be taken as a part of this specification, and wherein Figure 1 is a diagrammatic View in side elevation of one well-known type or" cableway in connection with whlch my invention is adapted to be used provements.

Mounted fixedly on the shaftfZZ to may be conveniently connected to the load. Inasmuch as the construction and arrange- ''ment just described does not in and of itself specifically constitute my presentinvention and embodies well-known arrangements and constructions being well-known to thoseskilled in the art, I do not deem it neces. sary to morefully illustrate or describe the same. 7,

' The improvements embodying my present invention relate more partlcularly to the construction of the winding engine for op"- eratingthe cables of the cableway above described, and I will now particularlydescribe the same, referring to Figs; 2 to 5, inclusive, of the drawings,

Referring particularly to Figs and 3,

the same including parallel side frames 20 mounted upon a suitable foundation, vnot shown, saidsideframes being connected rigidly by transverse members 21. The device includes the flanged drum 11 which is loosely rotate therewitlnis a drum-driving gearIQ l adapted to" be connected, by,, any suitable clutch means, to the head oft-he'druin '11;

said clutch means preferably comprising a friction ring 25 carried bythe said'gear and adapted; to f'rictionally engage Within a:

gjroove 2G (see Fig. 2), formed within the ad acent head or flange of theidruni 11. said friction clutch connection beingvestablished p or disconnected by moving the-said drum longitudinal of its shaft toward and away 4 from saidgearby means of' a suitable thrust mechanism, indicated generally at 27,i the,

same being'of any well-known suitable construction, for; example, that "of the general type, consisting of a thrust screw 28 located in a bore inthe axis" of the shaft, and acting upon :rtlirust pin, not shown, which in turn i exerts force upon rotation ofthe screw upon a cross-key -29 to exert pressure upon the head: of the drumsto move the latter length- V- wise ofthe shaft toward said 'gear. Reierse movement of the screw relieves the pressure H of said cross-key on the drum andpermits the drum to run free from its friction. The

thrust screw is turned/by a suitable hand lever 30 fixed thereto. 1 thrust mechanism specifically forms no part Inasmuch as this 7 of'my present invention, and is well-known in the art, I do DOt OOIISlClGI' lt necessary to describe or illustrate the same with greater particularity. The drum 11 is provided fwitli a circumferential braking surface 31,

adapted to be engaged by a brake-shoe 32 pivoted on an arm 33 on a brake-shaft' l, in V suitable bearings onthe frame, and ope'r-V able to apply and release the brakeby means of a foot lever 35. V

The drum 7 is loosely mounted upon :a

shaft 36, having suitable bearings 37 in the side frame, said drum being longitudinally movable of said shaft under control ,of'a

thrust mechanism 27 acting on a cross-key 29, and operable by a lever 30', in a manner similar to the thrust mechanism just described with reference to the drum 11. On

the shaft 36 is a drum-driving gear: 38 which meshes with the {rear 24L, heretofore described. The gear .38 is also' adapted to be connected to and disconnected from an end of the drum 7 by suitable clutch. means '25,

This hand brake may be of any'suitable well-known constructiongand I therefore do notrdeem it necessaryto describe tlie' 'same in greater detail; 1

it may be readily suppliedby thosesliilled in the art,

in order to check .or' control the revolution 7 .of the drum 7 when desired. 4 The lever 42 1S fulcruined at a point intermediate its ends It will be noted: that in'the embodiment shown,the drums 7,and 11 are of different diameters, the Ll].8,1l18t1,'(}'f the- Ill) shaft 76 mounted in suitable hearings in the y; inn, 4:9 designatesla any suitable sourcei for.example a boiler 56,'thesteam to the cylinders being controlled by a throttle 57 and handbperated throttle-valve shaft 58': (Fig. 3), in a welllznown manner.

Mounted loosely upon the power shaft and suitably held against endwise movement tlISlQODQlS a driving .pinion 59 which messes with the gear 2-1, heretofore described, said pinion being adapted to be connected to the power shaft by any suitable form of clutch which maybe operated to connect; said pinion to or disconnect it from the power shaft. The clutch may consist of a clutch sleeve 60 integralwith said pinion having suitable teeth 61 adapted to inter-engage teeth 62 on a clutch sleeve 63, slidably keyed,

as at 64:,to theshaft 49 to rotate therewith, and for movement longitudinally of the shafttoward. and. away from the said pinion 59., The sleeve 63 is provided with an annularigro ove 65 in whiclris arranged loosely a ring 66 to which are'pivotally connected at oppositepoints thereon, the ends of links 67, the opposite ends of which are pivotally connected, respectively, as at 68, to ends of the arms 69 of okev forming one of the members of a bell-crank lever 70, fulcrnmed,

as at 71, at a suitable point on the main frame. One member of the bell-crank lever is pivotally connectech. as at 7 2, to onev end of a connecting rod73, the opposite end of which is pivotally connected, as at Pi to a crank arm on a horizontal operating frame, and adapted to fb e rocked'by a hand lever 77 on said shaft, whereby the clutch member 63 may be moved 1n either dlrection longitudinally of the shaft to either connect the pinion 59 to said sl iaftor. disconnect it therefrom. It will be seen that when the pinion 59 is connected to 'the shaft 49. the gears 24 and 38. will. be positively driven, and that the drums will also bedri ven pro vided the clutch connections 25, 26 and 25, 26 are established. But on the other hand; said drums will not be driven from said pinion 59 if the latter is disconnected from its shaft, or thesaid drums are disconnected from their respective eearsQdand On the, opposite endoftheshaft 49 from that upon which the pinion 59-is'located, is loosely arranged. a drlving gear 78, the same being held against movement 1011 the shaft in a direction'toward the .side frame by a collar 7,9,held in a groove wSQiH L ll sha The gear 78 runs inniesli with 'the gear 39,

Suitable bearing rollers 93 'may be arranged between the adjaeent faces of the collar 89 and the sleeve 88, if desired. .Thesleeve 88 is provided with an arm 95 bolted, as at 96; to bracket.

9? rigidly connected to fthe main frame, whereby said sleeve 1s held against rotation on the said shaft. Threaded onto the shaft sleeve 88 is a clutclroperatmg member in the form of. a sleeve 98 havingan'overhanging yoke or arm "99 ,arranged'in an external annular groove 100 in the. hub 86, said sleeve 98 having an arm 101 rigid therewith and pivotallyfConnected, as at'102,'tc one end of a linlt103, the other end of which is connected, as at 104,. to an arm 105 on the '1'ock shaft 76, heretofore described. Suitable bearing rollers 106 maybe arranged between the .endsof the'sleeves 88 and QSand the adjacent face of the hub 86. The arrangement is suchthat when the sleeve 98 is ro- 'tated in one direction, it will act through the bearing; rollers 106 to exert pressurenpon the hub 86 to: move the clutch member 85 toward the member82, to thereby establish a driving connection between. such Qclutchmembers, and consequently a driving connection between the shaft 19 and the gear 78. lVhen the clutch is set. and the sleeve 98 is moved inthe opposite direction from that ust described, the overhanging 'arm 99.. will act. against the ad acent wall of the groove lOO to pull the member 85 away from the I116111bQIf-82 and thereby break the drivingconnection between the shaft 49 and the gear {Z8 and free .thelatter from driving con-. nection -with the shaft. v I y I l 'llhearrangement of the clutch connections with the-rock shaft 76 is such, thatwhen the lever"Z7 is. operated jtoclu tch the pinion 59 ,t th shet jethl here ash51 1emhen8 i b moved awayfronrthe member sens "disconthe members 110 and 111.

whereas, on the other hand, when the clutch permit the members 85 and 63'to take an in-- termediate position in whichneither pinion 59 or 7 8 will be connected to 'the shaft 49."

The drum 18 for operating the line 14 is mounted on a shaft 107 arranged in suitable bearings 108 in the side frame, and fixed on said shaft is a gear 109 bearing a friction clutch member 110, between which, vand a friction clutch thrust member 111 mounted on saidshaft, said drum 18 isarranged. The clutch thrust member 111 is operable by a suitable thrust mechanism 112, as heretofore described, tomove said member 111 against the adj ace-nthead of the drum 18 to thrust the latter lengthwise of the shaft into engagement with the clutch face 110, whereby said drum may be held in driving engagement with the gear 109. Vvhen the thrust is-relieved the drum may run free between The thrust 112 is operated by a suitable hand-lever 113. The drum is provided with a suitable brake surface 114, with which cooperates a brake shoe 115' on an arm 116 rigid with the shaft 46. 1

The operation of the invention, as above described, is as follows: If the carriage is located adjacent the headsupport A and it is desired to outhaul the carriage to a point where a load 1s to be taken, the clutch members 82, 85 are engaged, and the members 7 i 59, 63 disengaged, and the steam being admitted to the engine cylinders, the drum 7 will be turned'by the gears 78 and 39 to wind up the outhaul rope and thus pull the carriage toward the tail tower until the carriage reachesa point where the load is to be taken. As the end of the hoisting rope 9 cannot be pulled through the carriage, the latter when being outhauled will pull the said rope 9 with it. The outhaul drum 7 is driven at a higher speed while the outhaul cable is being wound up than during the inhauling operation of the carriage while the outhaul cable is being paid out, in order to save time in getting the empty carriage to the position where the load is to be received, and the frictions 25, 26 and 25, 26 being applied, and the pinion 59 running idle on the drive shaft 49, the inhaul drum is positively driven in the direction the r verse of its inhauling direction, so that the inhaul cable is positively paid out at ap proximately. the same rate as the outhaul cable is wound up, thereby preventing sag of the inhaul cable without the application of a brake. Then the carriage reaches the desired position, the clutch for the gear haul line is Wound in.

The friction for' the drum 18 is then disconnected, the frictions 25, 26 for the drum 11 are applied,

and the load is hoisted, the outhaul drum 7 being held stationary by the friction-band 41. Then the load has been raised to the desired point, the outhaul drum is connected to its gear 38, and the brake on said drum released, whereupon the inhaul drum 11 is operated through pinion 59 and gear 24 to take up the line 9 to thereby pull the carriage toward the head tower, the outhaul drum being driven bypinion 59, gear 24 and gear 38 to pay out the outhaul line at approximately the same speed at which the in- When the carriage reaches the point where the load is to be deposited, the engine is stopped, and the drums may be disconnected from their driving means, whereupon the load is lowered.

The driving gearing forthe drums, includtioned that the inhaul drum will take up the iigh outhauled at high speed by the drum 7. During the outhauling operation the drums are both connected with their driving gears 24 and 38 through the respective friction clutches, whereby said drums are interlocked, resulting in'theinhaul drum being positively driven, thus allowing the interlocking of the ropes in the form of an endless rope system. By this arrangement it is not necessary to disturb the frictions be tween the drums and their driving gears during normal operations, that is, inhauling or outhauling the carriage, except slipping the frictions when necessary in order to maintain proper relations and tensions between the ropes. This interlocking insures the inhaul drum during outhauling running at the approximate correct speed to pay out the inhaul line under the pull exerted on the carriage by the outhaul drum. 'Another advantage is that by having the drums interlocked when outhauling, less power is required, because the engine does not have to pull against friction due to the dropping and dragging of the cables among treestumps and rocks 111 the woods, which causes great loss of power. By having the interlock between the drums during outhauling, the cables are maintained substantially in proper relation and out of contact with the ground, rocks, etc., thus saving wear and tear on the cables, and also obviating the necessity of applying sufiicient friction to the drums to hold the cables elevated, which friction, of course, had to be opposed by sufficient power applied to the outhaul drum to outhaul the carriage. Furthermore, in systems where the inhaul drum is permitted to run free on its shaft, the shaft is continuously running in the opposite direction, with the result that during the out-hauling operation there is a high relative speed between the inhaul drum and its shaft, with the result that there is excessive wear of the bearings, and, in practice, the inhaul drum becomes loose 011 its shaft. In accordance with my invention this difiiculty is overcome, inasmuch as the inhaul drum runs with the shaft during the outhauling operation as well as during the inhauling operation.

What I claim and desire to secure by Letters Patent of the United States is 1. In a hoisting engine, a first drum shaft, a second drum shaft, drums on said shafts,

a drum-driving gear on each shaft, said gears being connected to be driven in opposite directions, a second drum-driving gear on said second shaft, a power shaft, a gear loose on said power shaft and meshing with the drum-driving gear on said first shaft, means for connecting said loose gear to the power shaft, a second gear loose on the power shaft and meshing with the second drum-driving gear on said second shaft, and means for connecting said second loose gear to the power shaft.

2. In a hoisting engine, a first drum shaft, a second drum shaft, drums on said shafts, a drum-driving gear on each shaft, independent clutch means for connecting eachdrum to its said driving gear, a second drum-driving gear on said second shaft, a power shaft, a gear loose on said power shaft and meshing with the drum-driving gear on said first shaft, means for connecting said loose gear to the power shaft, a secondgear loose on the power shaft and meshing with the second drum-driving gear on said second shaft, and means for connecting said second loose gear to the power shaft.

In testimony whereof I have hereunto signed my name.
